If the earth could make music, what kind of songs would it sing? This crazy contraption, called the Terrafon, actually lets us find out the answer to that question! Designed as a huge turntable tone arm and transducer, this musical instrument plays the earth like a big gravelly vinyl record. — Moe Beitiks

Harvest (2009) is a new art piece for the terrafon, traditional ensemble and cropland, by Alunda Kyrkokör (Olle Cornéer and Martin Lübcke). In the performance the Alunda Church Choir, conducted by Cantor Jan Hällgren, played the soil of northern Uppland (in Sweden). Harvest was exhibited at the Volt Festival in Uppsala in June. There is more to come. There are still many croplands still untouched by terrafon. The only thing needed is a powerful local musical ensemble that can sweat it out. This is a demanding piece and sound — well, take a listen:

The artist-duo also created the sound installation Bacterial Orchestra as well as an iPhone-generation of the same art piece, called Public Epidemic No 1. Olle Cornéer is also a electronic musician/producer/composer, while Martin Lübcke has a Ph.D. in theoretical physics (superstring theory).
